DANGER!Electric shock caused by high voltages insideWithin the device there are areas where high voltages may be present. Neverremove any covers.

There are no user-serviceable parts inside.

DANGER!Electric shock caused by short-circuitAlways use proper ready-made insulated mains cabling (power cord) with a pro‐tective contact plug. Do not modify the mains cable or the plug. Failure to do socould result in electric shock/death or fire. If in doubt, seek advice from a regis‐tered electrician.

CAUTION!Possible hearing damageThe device can produce volume levels that may cause temporary or permanenthearing impairment. Over an extended period of time, even levels that seem tobe uncritical can cause hearing damage.

Decrease the volume level immediately if you experience ringing in your ears orhearing impairment. If this is not possible, keep a greater distance or use suffi‐cient ear protectors.

NOTICE!Risk of fireDo not cover the device nor any ventilation slots. Do not place the device nearany direct heat source. Keep the device away from naked flames.

7 Plug and connection assignment

This chapter will help you select the right cables and plugs to connect your valuable equip‐ment in such a way that a perfect sound experience is ensured.

Please note these advices, because especially in ‘Sound & Light’ caution is indicated: Even if aplug fits into the socket, an incorrect connection may result in a destroyed power amp, a shortcircuit or ‘just’ in poor transmission quality!

Unbalanced transmission is mainly used in semi-professional environment and in hifi use.Instrument cables with two conductors (one core plus shielding) are typical representatives ofthe unbalanced transmission. One conductor is ground and shielding while the signal is trans‐mitted through the core.

Unbalanced transmission is susceptible to electromagnetic interference, especially at lowlevels, such as microphone signals and when using long cables.

In a professional environment, therefore, the balanced transmission is preferred, because thisenables an undisturbed transmission of signals over long distances. In addition to the conduc‐tors ‘Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfersthe signal, but phase-shifted by 180°.

Introduction

Balanced and unbalanced trans‐mission

Since the interference affects both cores equally, by subtracting the phase-shifted signals, theinterfering signal is completely neutralized. The result is a pure signal without any noise inter‐ference.

8 Troubleshooting

In the following we list a few common problems that may occur during operation. We give yousome suggestions for easy troubleshooting:

Symptom Remedy

The unit does not work 1. Check the power supply connection and the positionof the mains switch POWER.

No sound 1. Check the position of the rotary control LEVEL.

2. Check whether the LED SIGN/LIMIT lights up green. Ifit doesn't, the input signal is too weak

3. Check for correct signal cable connection.

4. Check the signal cable and/or the signal source.

5. Try using another signal cable.

Troubleshooting

active monitor

24

Symptom Remedy

Audible distortion Excessive input signal. Reduce the signal level.

Never operate the loudspeaker with such a high signallevel that the SIGN/LIMIT LED lights solid red!

Different channel levels (whenusing two monitors)

1. Make sure that for both channels the same type ofcable (balanced, unbalanced) is used.

2. Make sure that your speaker system is fully connectedand both speakers have the same input impedance.

Hum and noise 1. Use the ‘Ground/Lift’ switch, if applicable on all ampli‐fiers connected to the system.

2. Make sure that only balanced cables are used.

3. Make sure that all audio devices are connected on thesame power grid circuit and therefore share the sameground reference.

If the procedures recommended above do not succeed, please contact our Service Center. Youcan find the contact information at www.thomann.de.
